Slots with bonus rounds are popular because they may offer players extra time to play, without having to pay more credits. A bonus round can offer the chance to play a new game, often with some interaction. It’s triggered by certain symbols or combinations on the machine.
If your machine doesn’t have a label, check the pay table to see if it gives bonus rounds, and for what combinations.
Progressive slots are slots with a growing jackpot. They are often a group of slot machines linked together with a large jackpot sign flashing above. The jackpot grows with each play. Sometimes with progressives, you have to bet a certain amount to be able to win the jackpot – often the max bet.
Always read the paytable or ask a slot attendant to find out if you need to play a max bet to win a progressive jackpot.
